FOUNTAIN PEN.

Application filed January 7, 1925. Serial No. 1,014.

This invention relates to devices used in writing pens and especially pen-holders for holding and filling ink to be used through the holder by the pen that is held on the '5 holder.

One of the objects of this invention is to provide a simple structure by which a penholder can be filled by one operation.

Another object is to provide a pen-holder by which air can be ejected by the opening movement of a piston or other similar movable member while ink can be drawn into the holder by the return movement of the said member.

Another object is to provide a hollow piston in connection with a filling tube extending into the hollow of the piston to be closed by thetop termination of the hollow of the piston. f

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which Fig.1 is a general midsectional view of a simple form of apen-holder' with pen embodying the invention.

Fig. 2 is a fragmentary midsectional view similar to the illustration in Fig. 1, except having the top closing cap removed and hav- 30 ing the lower end broken 011', the piston being illustrated partly withdrawn from the ii older while shown in closed position in As illustrated in the drawing, the holder 3 is provided with overflow pockets or recesses 4 close to the lower end of the holder.

The whole structure, and the several details of the device as disclosed herewith is arranged so that the filling plunger ormember 5 is disposed in the lower end of the holder,

pass around the pisat a point that ink can ton or member 5 from theholder to the pen. Very little space is therefore preferably left below the piston 5 in the holder 3 when the piston is in its'lowermost position in the holder, or in closed and closing position.

The piston 5- is principally provided for filling purposes, and the closing'position is therefore to be understood to be the position so in which the filling facilities ofthis device are closed. i

Inrsuch closing or closed position of the iston, the ink in the holder must, of course, e allowed to pass towards the pen to be used in writing in the normal manner cus tomary with such pens and pen-holders.

The pen-carrier 6 is provided with a fil1ingduct or conduit or passage 7 A communieating tube 8 is provided in communication with the duct 7 and so as to exend upwardly from the pen-carrier 6 into the piston 5.

The piston 5 is provided with an upwardly extending tubular body 9, forming at the same time the handle member tnr the piston 5.

In the lower end, the piston is made to closely fit around the tube 8, while through the larger length of the upwardly extending body 9 ample space is provided-around the tube 8 within the body or handle member 9 for an ink-passage, as indicated at 10. The hollow of the body or handle 9 terminates short before the upper end 11 of the. handle, as indicated at 12. The termination of the hollow at 12 is intended to serve to close the upper end of the tube 8 in the normal clos: ing position when the pen-holder is being used for writing purposes.

From the hollow space 10, a communieating passage 13 is provided near the lower end of the handle as close as possible above the piston.

The pen-holder is provided with a closure in its upper end as indicated at 14.-

This closing member is provided with a bore through which the plunger extension 9 slidingly passes.

With this arrangement, the space above the iston 5 within. the holder 3 forms the inkolding compartment, while the ink may pass around the piston in the lower end of the holder to the pen. Air and old ink may under these conditions be thoroughly ejected from the inkholding compartment by an upward movement of the piston and handle, while the ink-passages and duct 19 between the ink-holding compartment and the on may be thoroughly cleaned by first having ink pass upwardly through such passages, and, followmg the upward movement of the piston, and then being e'ected again by' a downward movement of t e piston.

A movin of the piston 5 and the handle member 9 rom the outermost position back into the holder causes a cleaning of the lower penpassa es and at the same time causes a filling oft e ink-holding compartment above the piston in the holder 3.

Suitable packing can, of course, be vided at 15, 16 and 17, and at other points, if required, so that the ink-holdin compartment above thepiston must be y filled,

after the piston has once been moved to its uppermost position close to the closure 14, by moving the piston 5 back to its normal lowermost position in which the piston is illustrated in Fig. 1.

There can be no leakage if the difierent parts have been carefully arran ed as described above,--and a complete filling should be'possible with one back and forth operation of the piston'as described above.

The illustration in Fig. 2 shows the piston moved away from the normal writing or closing position. From this illustration it is clear that ink can only pass upwardly through the duct 7 and through the tube 8 past the top end of the tube 8 and then downwardly around the tube 8 through the space 10 within the handle 9 to escape through the assage 13 into the ink-holding compartment 18 in the holder 3, when the piston is moved downwardly into the holder, and nothing but ink can get into the inkholding compartment 18 as long as the device is held so that the lower termination of the duct 7 is always in ink while the piston i operated. It is also clear from this illustration in Fig. 2 that all ink and air must be ejected from the ink-holding compartment when the piston is moved upwardly, so that such matter will escapein the reversed order from the ink-holding compartment 18 through the passage 13 upwardly through the hollow 10 around the tube 8 over the top end of the tube 8 and then through the tube 8 to escape through the duct 7 out of the device.

The pen pointfeed duct 19, being of normal form, is. in this case in direct communication with the ink-holding compartment 18 by means of the overflow pockets or passages 4 in the barrel 3, whenever the piston is in its innermost normal and inoperative or closing position, as illustrated in Fig. 1.

Having shown the termination of the hollow 10 at 12 as in form of a conical valve to seat on the top end ofthe tube 8, it must be understood that another simplepacking may.

be inserted into the top termination of the hollow 10 in the extension-end or handle member 9 to serve as a suitable closing means between the handle member 9 and the tube 8.

Having thus described my invention, I claim:

1. In a pen-holder of the class described, a holder proper consisting of a proportionally thin-walled barrel, a pen-carrier disposed in the lower termination of the barrel, a filling tube extending from the said carrier upwardly into the barrel to a point near the top end of the barrel, a plunger disposed in the barrel having in its lower end a closely fitting portion surrounding the said tube and having through the larger portion of its length a proportionally wide elongated hollow to form a space around the tube when the tube is disposed within the hollow of the plunger, the upper end of the plunger being closed and adapted to close the tube when the plunger is in its lowermost position within the barrel, the plunger having a communicating opening from the lowermost termination of the hollow outwardly through the plunger, and aclosure in the upper end of the barrel having a bore through which the plunger is shiftably disposed.

2. In a pen-holder of the class described, a holder proper embodying a barrel, a pencarrier in the lower end of the barrel, and a closure in the upper end of the barrel; a piston disposed in the barrel having an up wardly extending handle-portion projecting through the to closure thereby leaving and forming an in -holding compartment within the barrel above the piston and below the said closure, the said barrel having overflows in its inner sides near the lower, end so that .mk can pass around the said piston when the piston is in its normal lowermost position from the ink-holding compartment to the en-carrier, the piston and handle member eing hollow with a narrow portion in the lower end to fit closely around a cooperating member while wider in the larger portion of the length of piston and handle portion, the upper end of the handle portion being closed, and a tube projecting upwardly from the said carrier and extending into the wide portion of the handle and adapted to be closed at its upper termination by the closed end of the handle, the handle-portion having a communicating opening just above the piston to form communication between the said ink-holding compartment and the inside of the handle.

3. In a pen-holder of the class described,

a movable ink-filling plunger consisting of a piston-portion and a handle-portion, the

plunger being hollow from the lower open end in the piston portion terminating short before the opposite end, the plunger having a communicating opening just above the piston through the handle into the hollow.

4. In a pen-holder of the class described, a pen-carrier having a filling duct in communication with an upwardly projecting tube, and a filling plunger being hollow and having means to fit snugly but shiftably over the tube and having means to form a filling communication through the duct and through the plunger around the tube and adapted to be shut off by the top end of the plunger. 7 i

5. In a pen-holder of the class described, a holder proper, a pen-carrier having a filling duct therethrough in communication with an, upwardly projecting tube, and a filling plunger being hollow and having means to fit snugly but shiftably over the tube within the holder proper and having means to form a filling communication through the duct and through the plunger around the tube and adapted to beshut off by the plunger from communication with the inside of the holder proper.

6. In a pen-holder, a barrel, a pen-carrier in the lower end of the barrel having a tubular extension-end projecting into the barrel and extending to a point near the top end of the barrel, a plunger having means to fit snugly around the tubular member in the lower part and having a comparatively thin tubular handle portion withmeans to allow an ejection of air and sediment through the first-named tubular member on the outward movement of the plunger from the barrel and 15 adapted to allow a drawing of ink into the barrel by an inward movement of the plunger.

In testimony that I claim the foregoing as my invention I have signed my name.
